Be it known that 1,.Gnonen S.-BENNETT, a citizen of the UnitedStates, residing at San Franciscoin the county of San Francisco and State of Oaliforniag'have invented a new and useful Gras-Regulator,V of. which the following is a specification.

This invention relates to gas-regulators. The object of .the invention` is to simplify the construction and .increasethe :eflicien'cy of devices of this character whereby they are,`

rendered linore sensitive in operation andare adapted-to controlthe flow of gasi'n a certain and positive manner irrespective of its pressure.l

A further Object isr` to'construct the regu-A;

lator' in -such manner that the valve may be adjusted from the` exterior without necessitating disconnection ofthe reg ulatorfr'iom .the pipes after it is once installed.

A further Object is to insure proper operation ofthe valve 4whether the regulatorpbe plumb or not. v f

Withthese and other objects in view,fas will appear as the nature of the invention is better understood, the same consists ofuthe novel construction and combination of parts of a gas-regulator, as will be hereinafter fully described and claimed. Y f

In the accompanying drawings,-forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there arelillustrated two forms of embodiment of the'invention each capable of carrying the same into practical operation, it being understoodthat the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure l is a view in vertical section through a gas-regulator embodying the essential features of the `present invention. Fig. 2 is a similar view ofa slightlymodified form. Fig. 3 is a horizontal sec-l tional view taken on the line 3 3, Fig. l. Fig. 4 is a similar View taken on the line 4 4, Fig. 2. Fig. 5 is a horizontal sectional view taken on the line 5 5, Fig. 2. Fig. 6 is a detached detail View of the valve shown in Fig. 1. Fig. 7 is a collective detail view showing the manner inlwhich thevalve ofthe regulator shown in Fig.11inayf.be adjusted. Fig. 8V is a,de tacheddetail View of a key or wrench for adj usting Athe valve shown inV Fig. 2.

Referring tothe drawings, and to Figs. 1, 3, 6, and] ,1 designates thefcasing of the regulator, the lower end of .which is threaded for connectionwith'ith'e inlet-pipe 2, one side of the casingh'ajvingan internally-threaded eX- tension zforconnection with the outlet-pipe :4.... `As thertwo pipes'may be of common or 'any preferred construction and as they perform' the usual function, further description is deemed. unnecessary. The upperportion Iofthec'asing has arranged within' it an in- {ver-ted '-cup' 5, whichlgmay be either integral with thelcasing'or secured thereto and is' spaced a sufficient distance from the inner walls'thereofto present a chamber (i,A in which works a iioat 7, vth'ec'hamber containing mercury to presentV anQeffective seal. The top 8 of the cnpis inset from" its upper end to present a chamber orspace to contain a body i,o f gas topconstitute a cushion'for the lioat,

said top being provided with a plurality of orifices 9, through whichzgas escapes beneath the float, and with "a Vcentral orifice l0, through which projects the upper portion of a lfloat-rod 1-1, which latter is secured to the float in any preferredA manner, preferably by the em ployment of two nuts 12,tu rned on a threaded length of the rod `and bearing, respectively, against the upper and under faces of the top of the float. Thev upper end of the rod is squared for engagement by a key when adjustment of the valve is necessary', as will presently appear. The valve 13 (shown in detail in Fig. 6) is a truncated conefpreferably7 dished beneath, and is provided in this instance with four radial arms 14, constituting guides to coact with the Walls of the bore of the casing to cause the valve to be maintained in operative position without interference with its freedom of action, the arrangement being such that the valve will be held against swaying, even though the regulator be tilted or be out of plumb. The lower portion of the valve coacts with a tapered valve-seat l5, formed in the lower-portion of the casing, the space between the periphery of the valve and the walls of the seat constituting a passageway for the gas. The valve has associated with it by a threaded connection 16 the lower end of the oat-rod 1l, which upon being turned will operate to raise and lower the valve to effect requisite adjustments. The lower portion of the valve carries a bifurcated extension 18, which is adapted to straddle a cross-bar 19, arranged at the bottom of the casing, the said bar operating to prevent the valve from turning when the same is being adjusted to adapt it to the pressure of gas passing through the regulator. Disposed on the top of the float are a plurality of weights 20, which are provided for the purpose of balancing the float, according to the pressure and supply of gas required, as is usual with devices of this character. It is a desideratum to obviate disturbing the weights when once installed; but with regulatorsin common use this is necessary. Both the disconnection of the casing from the pipe and the removal of the weights are obviated in the present deviceinasimple and thoroughly-effective manner and is accomplished by providing the casing with a detachable cap or cover 21, which may be associated therewith in any preferred manner, in this instance by providing the outer surface of its lower end with a circumferential channel 22 to be engaged by headed studs 23, projecting inward from the top of the casing, communication with the channel being effected through two alined recesses 24,

cut in the under side of the cap and communicating with the channel. When it is desired to adjust the valve, the cap is turned until the recesses 24 are opposite the studs 23, when it may be removed. A key 25 (shown in detail in Fig. 7) is then seated on the squared terminal 26 of the lioat-rod and upon being turned rotates the float and with it the rod 11, and as the valve is held from rotation through the coaction between the bifurcated extension 18 and the bar 19 it follows that the valve must be raised or lowered,according to the direction in which the float-rod is turned. By the arrangementshown the valve y can be adjusted to render it sensitive and positive in operation no matter what the pressure of the gas may be. By preference the valve is made of aluminium in order to avoid rust with consequent danger of binding.

In the form ot embodiment of the invention shown in Figs. 2, 4, 5, and 8 the main diierence resides in the manner of adjusting the valve and in the manner of holding it against turning while being adjusted. In this arrangement the casing is provided with two inward-projecting guides 27, in which work rods 28, carried by two alined radial arms 14, as clearly shown in Fig. 5. 1t will be seen that this arrangement will be thoroughly efcient in holding the valve against turning. The top of the cup 29 is inset for the same purpose as that described in connection with Fig. 1 and is provided with a central orifice 30, which performs the double 'reales function of a means for supplying gas beneath the float and also as a passage-way for the float-rod 1l. The top 31 of the float is provided with two sockets or openings 32 to be engaged by prongs 33 of a key 34, (shown in detail in Fig. 8,) and in order that the key may be brought into engagement with the sockets it will be necessary to remove the weights 20. The cap 21 is associated with the casing in the same manner as that shown in connection with Fig. 1. In operation the device shown in Fig. 2 is as etectivein every particular as that shown in Fig. l, and both devices will in a thoroughly reliable manner fulfil all of the requirements demanded of devices of this character.

While the construction and arrangements herein shown are illustrative of tWo operative devices, it is to be understood that the invention is not to be limited to the exact details shown as the different parts may be changed as to shape and proportion and still be Within the scope of the invention.
